cpusetGetCPUCount(3x)                                    cpusetGetCPUCount(3x)


NAME
     cpusetGetCPUCount - obtain the number of CPUs configured on the system

SYNOPSIS
     #include <cpuset.h>

     int cpusetGetCPUCount(void);

DESCRIPTION
     The cpusetGetCPUCount function returns the number of CPUs that are
     configured on the system.

EXAMPLES
     This example obtains the number of CPUs configured on the system and then
     prints out the result.

               int ncpus;

               if ( !(ncpus = cpusetGetCPUCount()) ) {
                   perror("cpusetGetCPUCount");
                   exit(1);
               }
               printf("The system is configured for %d CPUs\n",
                       ncpus);


NOTES
     cpusetGetCPUCount is found in the library "libcpuset.so", and will be
     loaded if the option -lcpuset is used with cc(1) or ld(1).

SEE ALSO
     cpuset(1), cpuset(5).

DIAGNOSTICS
     If successful, cpusetGetCPUCount returns a value greater than or equal to
     1.  If cpusetAttach fails, it returns the value 0 and errno is set to
     indicate the error.  The values for errno include those values as set by
     sysmp(2) and the following:

     ERANGE
          Number of CPUs configured on the system is not a value greater than
          or equal to 1.
